What if some day they will say: "goodbye and thanks for all the fish" :) whilst they launch an attack on people who bathe in the shallow waters, an attack that would make sharks go "daaamn"... that would be too obvious... but what if one day, while doing a double tulup with a screw they will unveal some major secret on us.. like in the end of "the sixth sense" or like in "matrix"...
to be honest... i really think that's possible, i really think that dolphins can one day make all your history, all your knowledge about mathematics and all your accomplishments become absolete...
a dolphin can make stephen hawking pretty effortlessly look like a horseshoe... which is not far
and on that bombshell it's time to end.
